There are some issues with the enetc driver, some of which are specific to the LS1028A platform, and some of which were introduced recently when i.MX95 ENETC support was added, so this patch set aims to clean up those issues.

There is an issue with one-step timestamp based on UDP/IP. The peer will discard the sync packet because of the wrong UDP checksum. For ENETC v1, the software needs to update the UDP checksum when updating the originTimestamp field, so that the hardware can correctly update the UDP checksum when updating the correction field. Otherwise, the UDP checksum in the sync packet will be wrong.
